Immunohistochemical expression of RON protein in the normal urothelium and bladder cancer cells. (A) Membranous expression of RON receptor was seen in a few non-neoplastic uroepithelial cells (highlighted by arrow). (B) The arrows indicate the membranous staining of RON receptor on cancer cells, representative of a low level of RON expression (original magnification × 300).
